T1566.001 Spearphishing Attachment
T1203 Exploitation for Client Execution
T1059.007 JavaScript
The PDF file contains a heuristic firing for a browser extension installation lure, indicating a social-engineering attempt to trick the user into installing potentially malicious software. The document also contains an external URI that appears to be part of a link farm, potentially used for SEO manipulation or to direct users to malicious content. While no scripts were directly extracted, the presence of a malicious PDF classification and the lure suggest an attempt to execute further malicious actions, possibly via embedded JavaScript or by prompting the user to download and run a payload.

Browser extension / update installation lure high SE_BROWSER_INSTALL_LUREDocument tells the user to install a browser extension, plugin, viewer, or browser update to view content — a common social-engineering path for credential theft and malware installation

Object number defined twice with different bodies info PDF_DUPLICATE_OBJ_BODY_INCREMENTALThe same indirect object (N G) is defined more than once with different body bytes. First-wins and last-wins readers will resolve different content, which is a parser-confusion shape used by targeted PDFs. Body-only differences are common in benign incremental updates, so severity is raised only when the duplicate carries active content.
-
Embedded URL info EMBEDDED_URLOne or more URLs were extracted from the document. The URL itself is not a detection — see the per-URL labels for which channel (macro, JS, link annotation, document body, ...) reached each URL.URL https://leonvi.ru/wix?keyword=dragon+age+inquisition+answer+a+request+from+hasmal PDF link annotation
